Subject: [RFC PATCH 15/08] [DEBUG] tools/lib/perf: Extend schedstats v17 headers to include the new debug fields

The previous commit hacked up schedstats v17 to add more fields.
Extend the header file for perf sched stats for analysis. These changes
depend on perf sched stats tools being developed in [1].
